ATLANTA, Georgia – The Atlanta Hawks booked a showdown with superstar LeBron James and his Cleveland Cavaliers as they notched one last double-digit victory over Miami to close out their National Basketball Association playoff series.

Joe Johnson scored 27 points on Sunday to lead the Hawks to a 91-78 victory over the Heat and that saw them win their Eastern Conference first-round series four games to three.

"I was just trying to be more aggressive," said Johnson, whose effort included a three-pointer from near mid-court that astounded Miami star Dwyane Wade. "I haven't put up a three that long in a while. I said, 'Forget it,' and just launched it. Making that got me into a little rhythm."

It was yet another lopsided win in a series that produced little drama, despite going the maximum seven games.

All seven games saw just 15 lead changes total - and none after the first quarter and each was decided by at least 10 points.

A close first quarter ended with the Hawks ahead 20-18, and they moved on steadily from there. Atlanta led 49-36 by halftime and by as many as 29 points in the final quarter, reaching the second round for the first time in a decade.

The Heat, led by Most Valuable Player candidate Wade, had forced game seven with a 98-72 victory on Friday.

Wade scored 31 points, but most of them came after Atlanta had established a comfortable cushion and it wasn't enough to extend Miami's season.

That the Heat were even back in the playoffs marked a remarkable turnaround from a woeful 15-67 record in their previous campaign.

"I'm very encouraged by this season," Wade said. "The team that won 15 games last year came back to win 43 games this year and took Atlanta to seven games in the playoffs. We've got something to build on."

Even though it wasn't close, there were some tense moments at the finish as Hawks fans taunted the Heat with a chant of "Hey, hey, hey, goodbye!"

Driving to the basket, Atlanta's Zaza Pachulia was seized around the neck by Miami forward Udonis Haslem, who was ejected for a flagrant foul.

Atlanta coach Mike Woodson, meanwhile, raced onto the court to make sure his players kept their cool, knowing he can't afford to have anyone suspended when the Hawks take on the top-seeded Cavaliers in a series that starts on Tuesday.

Atlanta hadn't won a first-round series since a victory over Detroit in 1999.

Last year they took eventual NBA champions Boston to a seventh game, but were routed in the decider.
